I just saw that movie a couple of weekends ago - it was better than I remembered it being. At the time I thought that plane was extremely unlikely looking, but now I can see that the set/model designer knew a little something about stealth technology. The special effects/flight scenes were pretty cheezy by today’s standard, though, or even compared to something like “Top Gun”.
Imagine what the visual effects would be like with CGI or digital green screen technology.
